I have had the "cracking sternum" problem off and on for a few years now. I believe I may have a solution. I noticed that my sternum began cracking a few months after I stopped working out, and then the pain progressed as time went on. It was only when I started working out again that the cracking and pain disappeared. This has happened to me three times and always during the part f the year when I let myself go and my chest muscles shrank. I believe that the natural tension from the muscular tissue when I was younger may have helped form my sternum and rib cage. Since my muscles shrink faster than the bones and ligaments can keep up. The whole support system becomes warped and allows the sternum to "crack." i hope this helps. I am off to find a better answer to what is occurring during the cracking sensation, but take my word on exercising your chest. It may take a few weeks but the pain will disappear along with the need to crack your sternum.But as always if the pain doesn't go away or gets worse see your doctor.
